IMPROVEMENT lN CARS FOR REMOVING GRAVEL AND EARTH ON RAlLROADS.

To (ZZZ whom it may concern:

Be it known that I, GRANVILL PALMER,

' of Greenbush, in the county of Rensselaer and State of New York, have invented a new and useful Improvement inR-ailroad Gravel or Dirt Cars; and I do hereby declare that thev following descri'ptiomtak en incounection with the accompanying drawings. hereinafter re ferred to, forms a full and exact specification of the same.

Of the drawings above mentioned, Figure 1 is a side elevation. Fig. 2 is an end elevation, and Fig. 3 a plan with some of the upper parts removed.

My improvement consists in applying be tween the box (or receptacle for the earth, gravel, &c.,) of the ear and the body or carriage frame of the same a turningtable or apparatus to permit the free turning of the box in any direction, so that the earth, &c., may be deposited on any desired spot or point of the road.

a a u. a, Figs. 1, 2, 3, is the body or carriage frame of the car, constructed in the usual mannenand having wheels I) b b I) connected to it in the ordinary way. 0 c is a circular railway arranged on the top of the body a a, &c.,- as shown in Fig. 3, and having an iron rail,

I d d, secured on its upper face by screws or nails or otherwise. 6 is a vertical or upright metallic shaft firmly attached at its lower end to the body of the ear, said shaft being held firm or sustained in its position by the metallie'bracing-shoulder f, Fig. 2, which is likewise secured to the body a a, &c., of the car, as shown in Fig. 3. The shaft 6 passes through asuitable hole in the center of the spider or axle-tree frame 1, (so that said spider or frame may turn freely on said shaft-,) the arms h h h h of which, at their ends, serve as axletrees for the friction wheels or rollers z i i i,

which rest andinove on the rail d d, as shown in Figs. 1, 2, 3. A circular plate, is 7:, somewhat larger in diameter than the railway c e, is arranged above the spider or frame so as to turn easily on theshaft c, which passes through a suitable hole in the center of said plate. A circular metallic rail or bar, 11, is attached to the under side of this plate It 7:, so as to rest upon the rollers 13 z i 2', and on the top of said plate k k the usual frame-work, a 'n, for elevating the box 121- of the car, is firmly attached, said car-box being hung on the same in the usual manner.

It will readily be perceived that by the above specified arrangement of machinery the carbox may be turned to any desired position on the body or carriage frame, and the contents be deposited at any part or point of the road. The proportions of the various parts are not stated in the above specification, as they are sufficiently defined by the drawings, and as they, as well as the materials' of which they are composed, are liable to variation by difference of views in builders.

It will be evident that other turning-tables or turning apparatus may be used, and therefore I do not confine my claim strictly and precisely to the kind above specified; but

WVhat I claim is- Arranging a turning-table or turning apparatus between the body or carriage frame of a railroad dirt-car and the box of the same, substantially as above set forth, so that said box (or the mouth of the same) may be turned to any particular part of the road and the contents deposited thereon.

In testimony that the foregoing is a true description of my said invention and improvement I have hereto set my signature this 1st day of J une, in the year 1842.

GRANVILL PALMER.
